CTG, NST, Perinatal outcome, Reduced fetal movements


Background: Reduced perception of fetal movement by mother is a common reason for self referral for assessment by healthcare providers affecting 5-15% of pregnancy. It allows early identification of fetuses at risk of adverse outcome. Non stress test (NST) or Cardiotocography (CTG) is the most commonly used test for antepartum and intrapartum fetal surveillance. Hence, this study was conducted to evaluate the role of NST/CTG in predicting perinatal outcomes in women presenting with reduced perception of fetal movements.

Methods: A prospective observational study was conducted on 110 term pregnant women presenting with reduced perception of fetal movements. NST/CTG was done as a preliminary test in them and the results were analyzed statistically.

Results: Total 60% women had reactive CTG, 17.3% had suspicious CTG and 22.7% had pathological CTG at the time of presentation. Out of 66 women who had reactive NST, 34 women were discharged after observation for 24 hours to follow up. About 58.15% women had one or more risk factors associated with pregnancy in our study. Pathological/ suspicious CTG was more commonly associated with adverse perinatal outcomes like presence of MSAF, low APGAR score at 1 minute and 5 minutes, neonatal distress, need for neonatal resuscitation and NICU admission with statistical significance. However, all babies had good outcome in our study.

Conclusions: Early approach, timely intervention could reduce associated complications and improve perinatal outcome in all these cases.
